Actual results: After loading, second page was not rendered. By changing the zoom, the second page rendered, but all graphics/images had black circles rendered in the upper left corner (see attached screen shot). The latter may be related to https://bugzilla.mozilla.org/show_bug.cgi?id=837461 Expected results: PDF should have rendered correctly. PDF renders correctly in acrobat reader.

Created attachment 733434 [details] PDF sample I attached the PDF document because the website is very slow.
Same result with FF20 and FF23, black circles in the upper left corner of graphics are visible. It appears only with HWA enabled.

It is specific to Windows graphics backend. PDF contains command moveTo(0,0)/lineTo(0,0)/closePath/stroke (see attached html) and that causes to draw a circle on Windows.

Thx Yury! I tried with FF 36 beta 1 & not able to recreate the issue. So, does it mean that the issue has been resolved? Appreciate the effort. -Vin
(In reply to Vin from comment #8) > Thx Yury! > I tried with FF 36 beta 1 & not able to recreate the issue. > So, does it mean that the issue has been resolved? I can still see the issue on FF 38 with PDFs and minimal test case. Make sure you are using hardware acceleration (check that at about:support).
Do have "Use hardware acceleration when available" checked. Have tried with few different articles & could not reproduce with FF 36 beta 1 & FF 34. Been a while that the issue was recreated...maybe few months ago. So, not sure what has been updated to resolve this? -Vin
Still a problem on my machine, Windows 7 SP1 with hardware acceleration on. I tried FF34 and FF 36b1 after your post Vin.
Ok, Nathan reminded me that this was only with the FF PDF Viewer...not sure why I forgot that...maybe been a while...so, yes, it still appears...work to do...:) -Vin
Going through the plugins, noticed that FF PDF Viewer (PDF.JS) is no longer compatible with FF 35 onwards. https://addons.mozilla.org/ro/firefox/addon/pdfjs/?src=userprofile Then this bug would be laid to rest? If yes, then, as the plugin is not removed, the issue still comes up with FF PDF Viewer being default. The solution being uninstalling the plugin manually. Is there a plan to remove it completely with any new forthcoming versions? If this is not the right place for this, appreciate if you can direct to the appropriate group/person. Thx. -Vin
Got an update on the support forum, seems a new version of the viewer is available on github, which is compatible with new versions of FF. Off-course that doesn't solve our black patch issue. Sorry for any confusion. -Vin
This issue remains in FF 54.0.1 Chrome has black lines the same vertical dimension as FF's ellipses.
The issue with the black circles in the upper left corner of figures still persists in Firefox 58.0.2. This is annoying. The issue occurs, for example, if I open the pdf version of this paper: https://www.sciencedirect.com/science/article/pii/S0016718514001444 I wonder why this issue has not been resolved for 5 years (?).
I am pretty sure this problem is exclusive to Elsevier (the scientific publishers) PDFs. I can recreate the problem using Elsevier created documents with other PDF viewers (not related to Mozilla) such as the chrome black line, or the circle effect in Edge. I think it is unrelated to the Mozilla viewer, and instead an error created when Elsevier embeds graphics into their PDFs. Elsevier is so tight on cash that I doubt they will be able to pay someone to fix it.
